Abstract

We test iterative algorithms, MR, QMR_γ5 and BiCG_γ5, to compare their efficiency in matrix inversion with multi-quarks (shifted matrices) within one iteration process. Our results on the 8³ × 12 and 16³ x 24 show that MR admits multi-quark calculation with less memory requirement, whereas QMR is faster for the single quark calculation.
